Ground clamps used to join multiple ground wires?

• A. Wire nuts
• B. Terminal block
• C. Ground clamps
• D. Fuses

Answer: (C)

When tying together several grounding conductors, the goal is a secure, low-impedance bond that remains reliable under service conditions. A ground clamp is designed to grip and electrically bond multiple ground wires to a grounding point, providing a solid, continuous path for fault currents and a durable mechanical connection to a panel, conduit, or grounding electrode. This makes it the best choice for joining grounds. In contrast, a terminal block is mainly a distribution or organization device for circuits, fuses protect against overcurrent and aren’t used to bond grounds, and while general-purpose connectors like wire nuts can join wires, they don’t offer the same robust, dedicated grounding bond you get with a clamp.
